them to rock slightly upon the pin a', to cause j vrecede from each other.

The carrier iscomposed of two parts, as shown more clearly in Figs. 3 anda. These two part-s, except 'at the forward end, have comparatively 'rhin sides, chamfeied on the outside from near the upper to the lower edge, as shown in Fig. 4. The-front part of the side pieces are thicker, as shown at p q, the former being Shorter, and the latter extends across the front of the former the entire width of the carrier. These parts are connected by a pin,

l r, formed upon or set into one of the pieces and projecting loosely into the other. The parts are fitted to eachother so as. to'allow as shown in Figs. 1, 3, and 4, that when the lever is in the positionshown in Fig. 2, between the sides of the carrier, it will bear against the projections tt, and thus throw out the lower sides of the carrier. This tips in the upper forward sides and causes the carrier to grip the cartridge. The forward end of the carrier is adapted torcceive the cartridge, being hollow, as shown in Fig. 3, and provided with beveled ears s s, which clamp the cartridge. forward position passes between these ears and separates the upper sides and ears, ready -to receive another cartridge. The sides of the carrier at their rear ends are provided with upward projections 17 17, and adapted to be struck by the shoulders 9 and l0 on the under -sideof thesliding bolt A. The position of the shoulder 9 is such that they strike the projec-A tion 17 as .the breech-block approaches its `rearmost limit, and the projections 10 are adapted to throw down the carrier as the bolt closes the breech.

The novelty of this construction .consists Ain the lateral rocking of the sides of the carrier.

In the operation of the arm thelmagazine is loaded at the side through an ordinary spring; trap. A cartridge or shell being in the chamber, suppose the lower end of the lever to be thrown lbrward. The first cfect of this movemeut will be to slide the bolt backward and begin to force the hammer to the full-cock notch. At the same time the forward portion of the lever drops away from the safety lever 7, and the sin-ing 8 then-begins to exert its The upper end of the lever 2 in its force. press the firingpin to its rearward limit of movement, thereby drawing the forward end of said pin even with or slightly within the face of the bolt, and by this movement, also, the notch 12 passes the rear end of the safety-4 lever, which, through the spring acting upon the shoulder 16, is forced into the notch, as shown in Fig. 2. A further movement ofthe lever forces the hammer tothe full-'cock notch and carries the breech-bolt back until the cartridge or shell is drawn from the barrel. The ejector is then struck by the shoulder 22 on the lever as the'upper end of the latter turns, and is l'orccd quickly outward, which has the effect of ejectiug the shell-or cartridge from the chamber. The same movement ofthe 1e- 'ver has also spread the lower edges of the carlricr sides and caused the ears s to grip the The first action of the spring is to cartridge, which has been forced back by the magazincspriug onto the carrier. The last part of the backward movement of the bolt also, by means of the shoulders 9 and 17 onthe boltand carrier, respectively, forces up the forward end of the carrier and presents the ,cartridge to the bore of the barrel. The return movement ot' the lever slides the bolt forward and at the same time relieves the pressure from the ejectorfpin, whiehjs thenl free to drop'baek into its place flush with the face of the bolt. The face ofthe bolt then strikes the head of the cartridge (the firingpiu being still held within the bolt by the safety-lever) and pushesitlinto the bore of the barrel, while the lever, spreads ythe sides of, the carrier. The last part of this return movement throws down' the carrier by the means before describedand brings the forward portion of the lever 2 to bear upon the safetylever 7 thereby forcing its rear end from the notch l2 and leaving the tiring-pin free to be acted upon by the hammer.

In the bottom plate of Fig. 1 we show a device which we term a safety-valve. It can be arranged in different ways and in any part or piece of the gun best suited for it. Sometimes the head of a cartridge blows otl in firing, and if the end ofthe bolt does not tit exactly against the barrel there is a great escape of ga-sinto the breeelnwhich is liable to swell or burst the receiver and disable the gun. By this arrangement, no matter how much gas escapes into the gbreech, this valve o ens and allows it't-o escape Without injury to he arm.

The following 4is a description: In Fig. l is shown'a valve, 23, swinging on the pin 30. It is arranged toswing outward. At 15 is represented'a spiral spring arranged to hold the valveclosed. The bottom plate is cut through into the interior. It is evident that when there is any gas-pressure on the inside the valve will be blown open, and when 'the pressure is gone the spring will close it again.

vVe claim as 'our inventionm 1. The combi nation, in abreech-loading firearm, of the 'slidingl bolt, a firing-pin having an enlarged rear end and shoulder, ll', said pin be-- IOC IIO

"substantially as describedu 2. Theeombination, in abreeeh'loading firearm, of the breech-bolt having a longitudinal bore, the 1iring-pin borne therein, having an enlarged rear end and flattened front end, the safety-lever pivoted to the bolt and fitted to a notch. in the liring-pin, the spri ng in the firingpin, the slotted upward extension of the lever2 through which the firing-pin passes and upon which the spring hears, and the slotted upper end ofthe lever 2, all substantial] y as described.

3. In a magazine iire-arin, a Carrier coniposed of two side pieces loosely pivoted at their rear ends upon a pin and pivoted to each other at their front ends to permitlateral roeking motion, in combination with inclined projeutions on the inner lower surfaces oi'said side pieces, at the rear thereof', and the operatinglever, the said lever spreading the upper part ofthe sides in advancing and closing the saine in retracting the bolt7 substantially as de* scribed.

4. In a magazine lire-arm of substantially tridge, one overlapping the other, and the longitudinal pivot vr, connecting the two parts and perniittinga roekingniotion, all substan tially as described.

5. In a brocoli-loading lire-arm7 a safety spring-valve in the bottoni of the receiver, consisting ol a valve, 23, pivoted upon a pin, 30, and having a rear projection adapted to receive the pressure ofthe spring 15, litted in a cavity in the receiver,wl1ereby the said valve is kept normally closed, but is adapted to open outward when the pressure from within exceeds the pressure of the spring.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
